Coupler
This gear coupler is a mechanical power transmission component with a sliding spring-loaded sleeve, designed for torque transfer between misaligned shafts. It is machined from alloy steel or carbon steel, with a standard bore diameter range of 12mm to 60mm and a maximum torque capacity of 1200 Nm. The coupling includes a keyway for shaft fixation and a grease fitting for lubrication maintenance.
The component is manufactured to DIN 5480 spline standards and features a hardened tooth profile with a surface hardness of 50-55 HRC, typical for industrial couplings. No plating or coating is specified, so the base material is expected to require external corrosion protection in humid environments. The sliding sleeve uses a spring mechanism to maintain axial contact under load, reducing backlash to under 0.25 degrees.
Buyers include manufacturers of agricultural machinery, automotive drivetrains, and industrial conveyors. The coupler is used in applications requiring high torque, moderate speed, and occasional misalignment. Packaging is in wooden crates, with 5 to 10 units per crate depending on size. Bulk orders are accepted, but no minimum order quantity is confirmed. Shipping is offered under FOB or CIF terms from Taizhou port.

Sourcing Coupler from Taizhou Hongbang Machinery Co., Ltd. - China Import Guide
Verify the material grade of the coupler before ordering, as alloy steel and carbon steel have different strength and corrosion profiles. Confirm the bore diameter tolerance, keyway dimensions, and spline profile against your shaft specifications. Request a material test report for tensile strength and hardness, even if not advertised.
Lead time is not stated; production may take 2 to 6 weeks depending on size and volume. Incoterms are FOB or CIF, but buyers must confirm whether port fees and insurance are included. Payment terms are unconfirmed; negotiate against a 30% advance and 70% against bill of lading to mitigate risk.
Inspect each coupler for surface cracks, burrs on splines, and proper grease fitting alignment. Request a sample batch for torque and backlash testing under load. Ensure the supplier provides a packing list with serial numbers and a certificate of origin. Without documented quality control, assume the product meets only basic commercial standards.
